Summary

isp.net

United States of America · AI-generated

residential isp lasvegas access

The AS handle ISPNET-AS is held by isp.net.

What it's used for

  • The address space carries residential and local access traffic, evidenced by reverse DNS pointers to isp.net, lv.net, and lasvegas.net (e.g., ip-64-250-247-254.isp.net).
  • With 37120 IPv4 addresses announced across 16 prefixes and only 7 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants are consistent with the announcer, appearing as isp.net or ISP.NET LLC across all sampled prefixes.
  • The inventory is a mix of large /19 blocks and smaller /22 to /24 allocations, with netnames like LASVEGASNETWORK2 and LVNETBLOCK3 suggesting a regional focus in Las Vegas.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,779 prefixes, as published 2026-10-23. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
